Apostle Nathaniel of the Seventy
Saint Nathanael, whose name means "the gift of God," was from Cana of Galilee (John 21:2). He was brought to the Savior by Phillip, as described in the Fourth Gospel (John 1:45-51). Christ calls him a true Israelite, which means "one who sees God." Nathanael was amazed when Christ says that He had seen him under the fig tree. Then He says that Nathanael will see even greater things; he will the heavens opened, and "the angels of God ascending and descending upon the Son of Man."
Saints John Chrysostom, Cyril of Alexandria, Epiphanios of Cyprus and other Fathers of the Church regard the Apostle Bartholomew (the son of Tholomai) as the same person as Nathanael. Thus, his name would be Nathanael, and his patronymic would be Bartholomew.
According to The Jerome Biblical Commentary (page 796), Nathanael was thought to be the same person as Bartholomew, because the latter's name followed Philip's in three lists of the Apostles (Matthew 10:2-5; Mark 3:14-19; and Luke 6:14-16). The Synoptic Gospels mention Bartholomew as one of the Twelve Apostles, but they do not mention Nathanael. On the other hand, Saint John's Gospel makes mention of Nathanael, but not of Bartholomew.
